Automatically Link to Twitter Usernames in Content : This is especially useful if you are running a website that focuses a lot on Twitter (probably a viral content site, etc.)
The following code snippet for functions.php converts all @ mentions in your content to their respective Twitter profiles.
Why dont I just use a plugin? Good question. The more plugins you have installed on your WordPress installation the slower your site loads. Remember search engines use your page load speed as a ranking factor. So if you want your SEO to be effective and your rankings increased on search engines, one must pay attention to SEO factors such as this. If your not comfortable with code or SEO we can help. Tap here.
For example, an @happy mention in your content will be converted to a link to the Twitter account “twitter.com/happy” (“happy” being the username):
function content_twitter_mention($content) {
return preg_replace('/([^a-zA-Z0-9-_&])@([0-9a-zA-Z_]+)/', "$1<a href=\"http://twitter.com/$2\" target=\"_blank\" rel=\"nofollow\">@$2</a>", $content);
}
add_filter('the_content', 'content_twitter_mention');
add_filter('comment_text', 'content_twitter_mention');
